DG-PSI Sequence Valve, 3 Way Normally Open, Internal Pilot<br />
HYDRAULIC SYMBOL<br />
DESCRIPTION<br />
10 size, 7/8-14 thread, “<strong>Delta</strong>” series, 3 way normally open internal pilot sequence valve<br />
OPERATION<br />
The DG-PSI in neutral (un-piloted), allows flow between (3) and (2) bi-directional, while blocking at (4).<br />
The spring chamber is constantly vented at (1).<br />
On attainment of a predetermined pressure at (4), the cartridge shifts to close (3) to (2), while opening (4) to<br />
(3).<br />
Note that the backpressure value at (1) must be added to the selected pressure setting to determine pilot<br />
pressure necessary to open valve.<br />
FEATURES<br />
• Optional spring ranges to 1500 PSI (103 bar).<br />
• Hardened parts for long life.<br />
• Industry common cavity.<br />
.030 to .060 diameter orifice recommended beneath port (4).<br />
